Hydropower Station Gantry Crane

Sự miêu tả

Hydropower Station Dam Top Gantry Crane is a special lifting equipment for hydropower stations. It is mainly for material handling and maintenance operations on the top of the dam. It consists of metal structure, lifting mechanism, walking mechanism and electrical control system. Metal structures include gantry (main beam, legs, end beam), driver's room and maintenance platform, with high-strength steel to ensure load-bearing capacity and stability. The lifting mechanism includes an electric trolley, a wire rope, a pulley set and a sling. Walking mechanism relies on the motor to drive the wheels to move along the dam top track to achieve the horizontal positioning. Electrical control system has frequency conversion speed regulation, limit protection and remote monitoring modules to ensure accurate and safe operation.

Dam top hydropower gantry crane is specially for maintenance and water scheduling of hydropower station gates. It has a compact structure and strong wind and earthquake resistance, which is suitable for harsh environments on the dam top. Its The modular design is easy to transport and install, and lifting mechanism can adapt to different types of gates (flat or curved). It is a key hydraulic machinery with high efficiency and high reliability, ensuring dam safety and water resource regulation.

Special Design Of Hydropower Gantry Crane

High wind resistance and stability

Wind-resistant design: Its design considers wind resistance, adopting structural design to ensure safe and stable operation under high wind speed.
Stability guarantee: The legs and track systems enhance the overall stability and prevent gantry crane from displaced or overturning due to wind or other external forces.

Anti-corrosion and waterproof functions

Corrosion-resistant materials: Considering the humid working environment and corrosive substances, the key components are made of corrosion-resistant materials, such as stainless steel, galvanized steel, etc., to extend service life.
Waterproof design: The electrical control system and other key components are waterproofed to ensure normal operation in humid environments. For example, sealed joints and waterproof housing can effectively prevent moisture from intrusion, avoid short circuits and other electrical failures.

Compact design and flexibility

Space optimization: The dam top space is limited, so it is more compact, reducing the footprint while maintaining sufficient lifting capacity and range. This compact design allows gantry crane to move flexibly in a narrow space to adapt to complex working conditions.
Multifunctional: It can not only carry out conventional material handling, but also for equipment maintenance, maintenance, with high adaptability.

Customized solutions

Customization for specific needs: According to different hydropower station needs, dam top gantry cranes can be customized, including load capacity, span, lifting height, etc. to meet specific engineering requirements.
Modular design: Adopts a modular design concept, which is easy to transport, install and disassemble. It is especially suitable for projects that require frequent transfer of construction sites, improving the operability and flexibility.

Main Application

Gate installation and maintenance
Dam top gantry cranes are mainly for lifting, dismantling and daily maintenance of various types of gates in hydropower stations (such as flat gates, arc gates, accident gates, etc.). When the unit is overhauled or the gate is damaged, hydropower gantry crane can quickly lift the gate to the maintenance platform. It is convenient to inspect, weld or replace parts and ensure the sealing and operational reliability of the gate.

Flood control dispatch and water level control
During the flood season, gantry crane could operate the flood discharge gate and the diversion gate to achieve accurate opening and closing. It controls the drainage flow, and avoids floods from flooding over the dam.

Cleaning and smearing grille maintenance
The water inlet of hydropower stations has barriers to prevent floating objects from entering the unit. Dam top gantry crane can install a grab bucket or a hydraulic grab beam to regularly clean blocked branches, garbage and other debris to ensure smooth water flow.
